Your rhesus status is fixed by your genes: If you're rhesus positive (RhD positive), it means that a protein (D antigen) is found on the surface of your red blood cells. Most people are RhD positive. If you’re rhesus negative (RhD negative), you do not have the D antigen on your blood cells.

As humans, we believe we evolved from apes and the Rh factor in our blood even derives its name from the Rhesus Macaque. But when it comes to the antigens in our blood there’s a small percentage of the population with a strange anomaly, leading some to question if Rh-negative blood is alien in origin.

If not, ask your doctor for a blood type test. 2018-05-01 · The false-negative rate (0.03%) was lower than the predetermined estimated false-negative rate of cord blood serology (0.25%).

If a woman with Rh-negative blood has not been sensitized, her doctor may suggest she receive RhIg around the 28th week of pregnancy to prevent sensitization for the rest of pregnancy.

There is no d antigen and Rhd is sometimes used to denote “RhD negative”. The most commonly occurring patterns in humans are: Dce, dce, DCe, dCe, DcE, dcE, DCE and dCE. These 8 have been given short forms R 0, r, R 1, r’, R 2, r”, R z, and r y.

African and Asian people with Rh negative blood usually always have a RhD gene it's just inactive. If they do have a deleted RhD gene it is caused by recent admixture with the Caucasian race. The intelligence agencies also prefer Rh negative people who possess the CCR5 Delta 32 gene, although this is not mandatory.

Those four main blood groups—A, AB, B, and O—can be Rh-positive or Rh-negative, meaning that there are 8 blood groups in total. When the researchers looked at this second classification, there was further good news—people in any blood group which is Rh-negative are also “somewhat protected” from the virus.

This is called the RH factor. The RH factor is the Rhesus (rhesus as in monkey) blood factor. A "positive" blood group means that the person has Rh antigen on the red blood cells whereas a "negative" blood group means that the Rh antigen is absent on the red blood cells.
